His 23-year-old girlfriend, who is the daughter of Seinfeld co-creator and frequent SNL guest star Larry David, said that her famous father "100 percent" approves of their relationship.

"He really loves that I'm dating a comedian," David shared. "He loves it because he feels like the only people he can talk to are people who also make jokes. It worked out very well."

As far as the riveting conversations the two comedic minds engage in, Davidson joked that he and the sitcom superstar talk "mainly about dinners and what we're gonna eat and how excited we are to eat and golf."

Davidson also opened up his girlfriend's role in his sobriety, explaining, "I'm very lucky. She's very, very supportive."

"I felt like, if I just kept it to myself nobody would know, but if everybody knows, then you kinda have to keep yourself in check so you don't let anybody down," he explained. "So I thought that was a good idea to do."
